About the collection

 In the photo, you can see the test tubes with the raw materials produced during refining crude oil: Bitumen, Kerosene, and diesel. Bitumen is a substance consisting of 83% carbon, 10% hydrogen, less oxygen, nitrogen, sulphur and other elements. In the modern world, there are several processed bitumens that are used for the production of materials for pavements and house roofs. Kerosene is a flammable liquid produced during petroleum refining. It is dark brown or yellowish, has a strong odour, and is one of the most important minerals. Diesel is a type of petroleum product. Like petrol, it is the most widely used fuel.
